Description and Introduction

EMIFIL (Inductor type) Chip Ferrite Bead (Array) BLA31A/BLA31B Series (1206 Size) The part **BLA31AG221SN4D** is a multilayer ceramic capacitor (MLCC) manufactured by **TDK**. Here are its specifications:

- **Capacitance**: 220 pF (221 = 22 x 10^1 pF)  
- **Tolerance**: ±0.1 pF (SN = ±0.1 pF)  
- **Voltage Rating**: 100 V  
- **Dielectric Material**: C0G (NP0) – Ultra-stable, low-loss dielectric  
- **Temperature Coefficient**: 0 ±30 ppm/°C (C0G characteristic)  
- **Termination**: Nickel barrier with tin plating (standard)  
- **Operating Temperature Range**: -55°C to +125°C  
- **Package Size**: 0603 (1608 metric) – 1.6 mm x 0.8 mm  
- **ESL (Equivalent Series Inductance)**: Low ESL design  
- **Applications**: High-frequency circuits, RF filters, timing circuits, and precision analog applications  

This capacitor is designed for high-reliability and precision applications where stable capacitance is critical.

Application Scenarios & Design Considerations

EMIFIL (Inductor type) Chip Ferrite Bead (Array) BLA31A/BLA31B Series (1206 Size)

Alternative Part Number

  • BLM31PG221SN1L --: Same 1206-size ferrite bead with 220 ohm impedance at 100 MHz and similar current rating, widely available and electrically close to the original.
  • MPZ3216S221AT000 --: 1206 ferrite bead with 220 ohm impedance at 100 MHz, comparable DC resistance and current handling, suitable drop-in substitute.
  • HCB1206KF-221T25 --: 1206 high-current ferrite bead with 220 ohm impedance, similar package and electrical characteristics, good alternative when Murata/TDK are unavailable.
  • FBMH3216HM221NT --: 1206 ferrite bead rated 220 ohm at 100 MHz, suitable alternative for noise filtering with similar current rating.
  • MPZ3216D221ATA0L --: Equivalent 1206 ferrite bead with 220 ohm impedance at 100 MHz from a major alternative supplier, suitable for the same noise filtering role.
  • HCB1206KF-221T60 --: 1206 high-current ferrite bead with 220 ohm impedance, offering comparable impedance characteristics as a cost-effective cross-reference.
